A single-bill currency dispenser incorporates a self-contained cartridge for storing a quantity of bills of a single denomination, and dispensing the bills singly in response to electrical control signals. The bills are loaded into the cartridge in a vertical stack of bills which may, if desired, be arranged in serial number order, and are dispensed one at a time from the top of the stack. The serial number of the bill next to be dispensed is visible through a window in the top of the cartridge case. A roller engages the topmost bill at the top of the stack and urges it forward to be received by a belt conveyor. Passage of a single bill through the conveyor triggers a switch to indicate that dispensing is occurring, and passage of two or more bills at the same time through the conveyor triggers a second switch, causing the bills to be ejected into an escrow tray. The cartridge is received and locked in place in a host machine, and correspondingly coded mechanical fittings allow insertion of an appropriate cartridge into place in the machine. When a locked case is desired, the case of the cartridge forms a locked self-contained unit, so the cartridge may be removed from the host machine without disturbing the security of the stack.
